Looks like sequential operation to me:

1. pdns sends a query to mariadb (goes to sleep waiting for response)

2. mariadb processes the query and sends back the response

3. pdns processes the response, then sends the next query to mariadb

etc.

Without overlapping requests, pdns and mariadb will never be working at 
the same time.
